Chauvin Arnoux p03652908 SK8 self-locking sensor for pipes, -50°C to +140°C content_copy

The Chauvin Arnoux SK8 is a self-retaining temperature sensor for temperature measurements on pipe lines. It is based on the technology of a K-thermocouple, which is wrapped around the pipe to be measured using a copper band with integrated hook-and-loop tape fastening. This construction enables quick and secure installation without additional fastening means. The sensor is specifically designed for use on pipes with a diameter between 10 mm and 90 mm and is suitable for applications in industrial measurement technology where non-invasive temperature measurement is required.

Applications
The SK8 is primarily used in process and plant monitoring, where continuous temperature measurement on pipe lines is necessary. Typical application scenarios include monitoring heating and cooling circuits, steam lines, or fluid flows in the chemical industry, food processing, or power generation. The hook-and-loop tape fastening allows flexible adaptation to different pipe sizes and enables quick installation without tools.

Functions and Equipment in Detail
The sensor features a measurement range of -50 °C to +140 °C, making it suitable for a wide range of industrial applications. The response time is 10 seconds on stainless steel pipes, ensuring a rapid reaction to temperature changes. The total length of the sensor is 32 cm, providing sufficient length for attachment to pipes within the specified diameter range. The combination of copper band and hook-and-loop tape ensures a stable and even contact surface with the pipe surface, supporting measurement accuracy.

Technology Explained Simply
A K-thermocouple generates an electrical voltage proportional to the temperature difference between the two ends of the thermocouple. This voltage is evaluated by a suitable measuring device (e.g., a temperature meter or data logger). The copper band of the SK8 serves as a mechanical support structure and improves heat transfer to the pipe surface. The hook-and-loop tape fastening enables simple, repeatable mounting and dismounting without damaging the pipe. The construction is designed so that the sensor is placed directly on the pipe surface, enabling indirect but reliable temperature measurement.

Compatibility and Accessories
The SK8 is designed for use with measuring devices that support K-thermocouples. It is not suitable for direct mounting on flat or non-cylindrical surfaces, as the hook-and-loop tape fastening is specifically designed for pipes with a diameter between 10 mm and 90 mm.

Mounting and Installation
Installation is performed by wrapping the sensor around the pipe using the hook-and-loop tape. The hook-and-loop tape fastening ensures a secure hold. No additional fastening or tools are required. Positioning should be done so that the sensor is placed as close as possible to the point where the temperature is to be measured. Even distribution of the hook-and-loop tape ensures optimal contact surface.

Advantages in Operation
The SK8 offers quick and easy installation without requiring process interruption. The non-invasive measurement protects the pipe from damage. The hook-and-loop tape fastening allows repeatable mounting and dismounting, which is advantageous for maintenance work or checking multiple pipe lines. The response time of 10 seconds on stainless steel pipes ensures timely reaction to temperature changes, which is important for process monitoring.
